Apphcation filed September 16, 1907. Serial No. 393,112.

To all whom it may concern:

Be it known that l, RODMAN ODELL, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Iniprovements in Carburetors for Hydrocarbon- Engines; and I do hereby declare the followingto be a full, clear, and exact description of the same, such as will enable others skilled in the art to whicl it appertains to make and use the same. a

This invention relates to a novel construction in a carburetor adapted to saturate air with hydro-carbon vapor and supply such air to the 'limit of capacity of the inlet to said carbureter to a hydro-carbon motor or other point of consumption, the object being to provide a small compact device of this character particularly adapted for use on automobilesto supply initial starting charges to the motor, and consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings illustrating this invention: Figure 1- is a central horizontal section of a carbureter constructed in accordance with my invention. Fig. -2 is a central vertical transverse section of the same;

My said carbureter has, as stated, for its object, to provide a small compact device which will completely saturate relatively large quantities of air with hydrocarbon vapors, and Which, therefore, is particularly adapted for use on automobiles in connection with the motor starting means formin subj ect of a companion application filed of even date'herewith.

- In starting hydro-carbon motors b the introduction of 'carbureted air into the compression chambers by means of a compressor other than the motor itself, it is absolutely essential that such air should be saturated with hydro-carbon vapors in order that the air or roducts of combustion contained in said cylinders may be so far enriched by the carbureted air thusintroduced to constitute a combustible mixture exploclible by a spark to start said motor. V

My said carbureter consists preferably of a cylindrical casing A closed at its ends and provided between its endswith an inletfor air and hydro-carbon liquid, the latter being admitted through the pipe B having a reduced delivery nozzle 0 enteringthe inlet.

chamber D centrally thereof, and said air being admitted to said inlet chamber through the perforations E in the cylindrical wall of said chamber and surrounding said nozzle. The said inlet chamber D is filled with loose cotton waste or the like upon which the hydrocarbon liquid drops and through which the air passes. The chamber A is lincd in- 'ternally.with an absorbent fabric such as lamp wick as indicated at F, such lining be ing held in contact with the inner faces of the walls of the chamber A by means of wire cloth G or the like.

The outlets H for carbureted air consist of tubes passing radially through the cylindrical wall of the chamber A and tl'irough the lining F and wire cloth G, terminating centrally of said. chamber A. l

A pet-cock I is providedtoydrain ofi superfluous liquid in the event that the latter is fed in too great quantities. The hydro-carbon liquid admitted primarily saturates the waste contained in the inlet chamber and passes thence upon the lining F moistening or saturating the latter, the absorbent properties of the latter causing the liquid to be distributed over the entire area of said lining.

The air contained in said chamber being completely surrounded so to speak, by the very volatile liquid, becomes saturated with vapor very rapidly while all air admitted passes through the saturated waste and lin-- mg. Hence, all air withdrawn through the outlets His completely saturated with the hydrocarbon vapor and when it enters the cylinders of the motor and commingles with the air and gases therein contained, enriches the latter to an extent sufficient to render the same combustible.

My said carbureter is adapted only for use in starting the motor, the carbureted air being too rich. for continuous operation of the motor.

I claim as my invention:

1. A carbureter com rising a receptacle equipped internally with a linin of absorbent material such as lamp whit, an inlet chamber communicatin with said receptacle at its upper end, air in ets to said chamber, an inlet for hydro-carbon li uid to said chamher, an absorbent filling sue as cotton waste therein, and outlets for air assing through a wall 0f said receptacle an terminating inof the lining thereof. carburetor comprising a receptacle equipped internally with a lining of absorbent material such as lamp wick, WiIG ,cloth disposed inwardly of said lining and serving to hold the latter against displacement, an inlet chamber communicatingfwith 'said receptacle at its upper end,- air inlets to said chamber, an inlet for hydro-carbon liquid to said chamber, an absorbent filling such as cotton waste therein, and outlets for air passing through a wall of said receptacle and ter- 10 minating inwardly oi the lining thereof.

In testimony whereof I have signed my name in the presence of two subscribing Witnesses.
